Description

Technical Field

[0001] This invention relates to the field of display technology, and more specifically to a display splicing device and a splicing display device. Background Technology

[0002] Due to current technological limitations, large-size displays require the use of splicing display devices. These devices stack displays sequentially in rows and columns. If any individual display is damaged, it needs to be rotated at a certain angle for easy disassembly. However, the stacked arrangement of adjacent rows of displays causes the rotation of the display to be disassembled to rub against its adjacent panels in those rows, posing a technical problem that increases the difficulty of disassembly and further restricts rotation.

[0003] Therefore, there is an urgent need for a display splicing device and a splicing display device to solve the above-mentioned technical problems. Summary of the Invention

[0020] N is an integer greater than or equal to 2.

[0021] Preferably, along the direction away from the base, the length of the second through hole connected to the first group of bearing members in the first direction is greater than or equal to the diameter of the rotating shaft of the first group of bearing members in the first direction;

[0022] Wherein, the length of the first through hole connected to the first group of bearing members in the first direction is greater than the length of the second through hole connected to the second group of bearing members in the first direction.

[0023] Preferably, the distance adjustment assembly includes a first distance adjustment member and a second distance adjustment member located at both ends of the base along a second direction, the second direction intersecting the first direction;

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Furthermore, it should be understood that the specific embodiments described herein are only for illustration and explanation of the present invention and are not intended to limit the present invention. In the present invention, unless otherwise stated, directional terms such as "upper" and "lower" generally refer to the upper and lower positions of the device in actual use or operation, specifically the drawing directions in the accompanying drawings; while "inner" and "outer" refer to the outline of the device.

[0040] Currently, in splicing display devices, there are technical problems such as easy damage to the display screen and high disassembly difficulty during the disassembly process.

[0041] Please see Figures 1a to 1b , Figures 2a to 2b This invention provides a display screen splicing device 100, comprising:

[0042] Base 110;

[0043] The support component 120 is fixedly connected to one side of the base 110.

[0044] The distance adjustment component 130 is disposed on the same side of the base 110 as the support component 120;

[0045] The support component 140 is connected to the support component 120 and the distance adjustment component 130. The support component 140 includes at least two sets of support members 141 arranged along a first direction Y, which is parallel to the extension direction of the support component 120.

[0046] The distance adjustment component 130 moves along the first direction Y, causing at least one set of the bearing members 141 to move in the same direction as the distance adjustment component 130.

[0047] In this embodiment of the invention, by setting up a distance adjustment component 130, when the distance adjustment component 130 moves relative to at least one set of support members 141 along the first direction Y, it drives at least one set of support members 141 to move in the same direction as the distance adjustment component 130, so as to increase the distance between the at least one set of support members 141 driven by the distance adjustment component 130 and the support members 140 adjacent to it in the first direction Y, thereby facilitating the disassembly of the display screen on the support member 140 and reducing the damage to the display screen caused by disassembly.

[0048] The technical solution of the present invention will now be described in conjunction with specific embodiments.

[0049] Please see Figures 1a to 1b ,and Figures 2a to 2b In this embodiment, the distance adjustment component 130 includes a plurality of first through holes 131 arranged along the first direction Y, and a group of supporting members 141 extending into one of the first through holes 131. Each group of supporting members 141 extends into a corresponding first through hole 131 to achieve connection between each group of supporting members 141 and the distance adjustment component 130, thereby facilitating the distance adjustment component 130 to control the movement distance of the corresponding supporting member 141 in the first direction Y through the length of each first through hole 131. The supporting member 141 is used to support the display screen. Therefore, the distance adjustment component 130 controls the movement distance of the display screen connected to the corresponding supporting member 141 in the first direction Y through the length of each first through hole 131.

[0050] Please see Figures 1a to 1b ,and Figures 2a to 2bIn some embodiments, along the direction away from the base 110, the lengths of the plurality of first through holes 131 in the first direction Y decrease sequentially; the length of the first through hole 131 in the first direction Y is, along the first direction Y, the distance between the end of each first through hole 131 near the base 110 and the end of the first through hole 131 away from the base 110. The lengths of the multiple first through holes 131 decrease in the direction away from the base 110. When the distance adjustment component 130 moves in the direction away from the base 110, it first causes the group of supporting members 141 furthest from the base 110 to move relative to the other supporting members 141. Subsequently, in the direction close to the base 110, the multiple groups of supporting members 141 move relative to the base 110 in sequence, and the moving distance decreases in sequence, until the supporting member 141 where the display screen to be disassembled is located moves relative to the base 110 and increases the distance between it and the adjacent display screen in the first direction Y, so as to facilitate the disassembly of the display screen and reduce the damage to the display screen caused by the disassembly process.

[0051] Please see Figures 1a to 1b ,and Figures 2a to 2b In some embodiments, the distance adjustment assembly 130 includes a first distance adjustment member 132 and a second distance adjustment member 133 located at both ends of the base 110 along a second direction X, the second direction X intersecting the first direction Y. The bearing member 141 extends along the second direction X and is connected to the first distance adjustment member 132 and the second distance adjustment member 133 respectively.

[0052] Please see Figures 1a to 1b ,and Figures 2a to 2b In some embodiments, each of the first through holes 131 includes a first sub-through hole located in the first distance adjusting member 132 and a second sub-through hole located in the second distance adjusting member 133, and each set of the bearing members 141 extends along the second direction X into a first sub-through hole and a second sub-through hole respectively.

[0053] In some embodiments, along the extending direction of the support member 141, the orthographic projection of the second sub-through hole onto the first distance adjustment member 132 coincides with the first sub-through hole. This ensures that when the distance adjustment assembly 130 controls the movement of the support member 141 along the first direction Y, the control effect of each first sub-through hole and the corresponding second sub-through hole on the movement of the support member 141 is consistent, preventing the support member 141 from tilting towards the first distance adjustment member 132 or the second distance adjustment member 133 during movement, thereby avoiding damage to the display screen.

[0054] Please see Figures 1a to 1b ,and Figures 2a to 2b In this embodiment, the support component 120 includes a plurality of second through holes 121 arranged along the first direction Y, the first through hole 131 and the second through hole 121 are respectively arranged in a one-to-one correspondence, and a group of the bearing members 141 extend into a second through hole 121.

[0055] The support assembly 120 is fixed to the base 110. Each set of the bearing members 141 extends into a corresponding second through hole 121 to obtain support force, thereby arranging multiple sets of bearing members 141 along the first direction Y. When the splicing display device is in normal working condition, that is, when the distance adjustment assembly 130 is not moving relative to at least one set of bearing members 141, the portion of each bearing member 141 extending into the second through hole 121 directly contacts the end of the second through hole 121 near the base 110 in the first direction Y.

[0056] Please see Figures 1a to 1b ,and Figures 2a to 2b In some embodiments, along the second direction X, the support assembly 120 is located between the first distance adjustment member 132 and the second distance adjustment member 133. By positioning the support assembly 120 between the first distance adjustment member 132 and the second distance adjustment member 133, it facilitates operation when the splicing display device is in a display screen replacement state (e.g., when...). Figure 2a , Figure 2b , Figure 4a or Figure 4b As shown in the figure, when the distance adjustment component 130 drives at least one set of the bearing members 141 to move relative to at least one set of the bearing members 141 along the first direction Y, the distance adjustment component 130 is manually or electrically controlled.

[0057] In some embodiments, the support assembly 120 includes a first support member 122 and a second support member 123 respectively fixed to both ends of the base 110 along the second direction X. The first support member 122 is located on the side of the second support member 123 closer to the first distance adjustment member 132. Each second through hole 121 includes a third sub-through hole located in the first support member 122 and a fourth sub-through hole located in the second support member 123. Each set of bearing members 141 extends along the second direction X into one of the third sub-through holes and one of the fourth sub-through holes, so that both ends of each set of support members in the second direction X obtain sufficient support force in the working state.

[0058] In some embodiments, along the extending direction of the bearing member 141, the orthographic projection of the fourth sub-through hole on the first support member 122 coincides with the third sub-through hole, so that the supporting force obtained by both ends of each set of bearing members 141 in the second direction X is equal when in operation, thereby avoiding damage to the display screen caused by uneven force on both ends of the bearing member 141 in the second direction X.

[0059] Please see Figures 1a to 1b and Figures 2a to 2b In some embodiments, the lengths of the plurality of second through holes 121 in the first direction Y increase sequentially along the direction away from the base 110. The length of each second through hole 121 in the first direction Y is the distance between the end of each second through hole 121 closest to the base 110 and the end of the second through hole 121 furthest from the base 110 along the first direction Y. Because, under the action of the distance adjustment component 130, the group of support members 141 furthest from the base 110 moves first and moves the greatest distance in the first direction Y, and the moving distance of the multiple groups of support members 141 decreases along the direction closest to the base 110, accordingly, the lengths of the plurality of second through holes 121 in the first direction Y increase sequentially along the direction away from the base 110, so as to avoid the length of the second through holes 121 restricting the moving distance of the support members 141, resulting in the display screen to be disassembled not being spaced apart from the adjacent display screen in the first direction Y.

[0060] In some embodiments, the length of any of the first through holes 131 in the first direction Y is greater than or equal to the length of the largest of the plurality of second through holes 121 in the first direction Y. When the splicing display device is in a display replacement state (e.g.) Figure 2a , Figure 2b , Figure 4a or Figure 4b As shown, since the actual moving distance of each group of the bearing members 141 needs to be controlled by the distance adjustment component 130, that is, it needs to be controlled by the length of the corresponding first through hole 131 extended to by each group of the bearing members 141 in the first direction Y, the length of any first through hole 131 in the first direction Y is greater than or equal to the length of the largest length of the plurality of second through holes 121 in the first direction Y, which helps to avoid the length of the second through hole 121 in the first direction Y from limiting the actual moving distance of the bearing member 141.

[0061] In some embodiments, the distance adjustment component 130 is separately disposed from the base 110, when the splicing display device is working normally (e.g., ...). Figure 1a , Figure 1b , Figure 3a or Figure 3b As shown, the distance adjustment component 130 provides support through the bearing member 141, so that the portion of each bearing member 141 extending into the first through hole 131 is in direct contact with the end of the first through hole 131 away from the base 110 in the first direction Y.

[0062] In some embodiments, the support assembly 140 includes N groups of support members 141 arranged along the first direction Y. Along the direction away from the first direction Y, the group of support members 141 closest to the base 110 is the first group of support members 141, and the group of support members 141 furthest from the base 110 is the Nth group of support members 141, where N is an integer greater than or equal to 2.

[0063] Along the direction away from the base 110, the length of the first through hole 131 connected to the m-th group of bearing members 141 in the first direction Y is equal to the length of the second through hole 121 connected to the (N-m+1)-th group of bearing members 141 in the first direction Y. Here, m is an integer greater than or equal to 1 and less than or equal to N. Along the direction away from the base 110, the lengths of the plurality of first through holes 131 in the first direction Y decrease sequentially, and along the direction away from the base 110, the lengths of the plurality of second through holes 121 in the first direction Y increase sequentially. When the lengths of the first through holes 131 and the second through holes 121 in the first direction Y satisfy the above relationship, it is beneficial for the distance adjustment component 130 to control the movement distance of the bearing member 141 in the first direction Y without being limited by the length of the second through hole 121 in the first direction Y, and to set the corresponding length of the second through hole 121 in the first direction Y according to the length of the first through hole 131 in the first direction Y, thus simplifying the design.

[0064] In some embodiments, along the first direction Y, the length difference of the first through hole 131 connected to any two adjacent groups of the bearing members 141 in the first direction Y is the same, which is beneficial for the distance adjustment component 130 to move the multiple groups of bearing members 141. The distance that adjacent groups of the bearing members 141 can be separated by the same distance in the first direction Y. For example, the length difference between the first through hole 131 connected to the k-th group of bearing members 141 in the first direction Y and the length of the first through hole 131 connected to the (k-1)-th group of bearing members 141 in the first direction Y is the (k-1)-th difference, where k is an integer greater than 3 and less than or equal to N; the length difference between the first through hole 131 connected to the second group of bearing members 141 in the first direction Y and the length of the first through hole 131 connected to the first group of bearing members 141 in the first direction Y is the first difference; the first difference is the same as the (k-1)-th difference.

[0065] Please see Figures 1a to 1b ,and Figures 2a to 2b In some embodiments, the load-bearing member 141 includes a pivot 141a that extends into the first through hole 131 and the second through hole 121.

[0066] In some embodiments, the rotating shaft 141a may be cylindrical or elliptical. When the rotating shaft 141a is elliptical, the diameter of the rotating shaft 141a in the first direction Y is the maximum distance between the end of the rotating shaft 141a near the base 110 in the first direction Y and the end of the rotating shaft 141a away from the base 110 in the first direction Y.

[0067] In some embodiments, each of the pivot members 141a includes a first pivot portion located within the first through hole 131, a second pivot portion located within the second through hole 121, and a third pivot portion other than the first and second pivot portions. Wherein, the diameter of the first pivot portion of at least one pivot member 141a in the first direction Y is less than or equal to the diameter of the third pivot portion in the first direction Y, and / or, the diameter of the second pivot portion of at least one pivot member 141a in the first direction Y is less than or equal to the diameter of the third pivot portion in the first direction Y. When the diameter of the first or second pivot portion of a pivot member 141a in the first direction Y is less than the diameter of the third pivot portion in the first direction Y, it is advantageous to prevent the pivot member 141a from moving in the second direction X, thereby preventing damage to components such as the display screen caused by the pivot member 141a detaching from the first through hole 131 or the second through hole 121. Preferably, the diameter of the third rotating shaft portion of the rotating shaft 141a in the first direction Y is greater than the length of the first through hole 131 connected to the rotating shaft 141a in the first direction Y; and / or, the diameter of the third rotating shaft portion of the rotating shaft 141a in the first direction Y is greater than the length of the second through hole 121 connected to the rotating shaft 141a in the first direction Y.

[0068] Please see Figures 1a to 1b ,and Figures 2a to 2b In some embodiments, along the direction away from the base 110, the length of the first through hole 131 connected to the Nth group of bearing members 141 in the first direction Y is greater than or equal to the diameter of the rotating shaft 141a of the Nth group of bearing members 141 in the first direction Y. Specifically, the length of the first through hole 131 connected to the Nth group of bearing members 141 in the first direction Y is greater than or equal to the diameter of the first rotating shaft portion of the rotating shaft 141a of the Nth group of bearing members 141 in the first direction Y.

[0069] The length of the second through hole 121 connected to the Nth group of bearing members 141 in the first direction Y is greater than the length of the first through hole 131 connected to the (N-1)th group of bearing members 141, so that when the Nth group of bearing members 141 and the (N-1)th group of bearing members 141 move in the first direction Y, the distance between them can be increased.

[0070] Please see Figures 1a to 1b ,and Figures 2a to 2bIn some embodiments, along the direction away from the base 110, the length of the second through hole 121 connected to the first group of bearing members 141 in the first direction Y is greater than or equal to the diameter of the rotating shaft 141a of the first group of bearing members 141 in the first direction Y. Specifically, the length of the second through hole 121 connected to the first group of bearing members 141 in the first direction Y is greater than or equal to the diameter of the second rotating shaft portion of the rotating shaft 141a of the first group of bearing members 141 in the first direction Y.

[0071] The length of the first through hole 131 connected to the first group of bearing members 141 is greater than the length of the second through hole 121 connected to the second group of bearing members 141, so that when the first group of bearing members 141 and the second group of bearing members 141 move in the first direction Y, the distance between them can be increased.

[0072] In some embodiments, the formula for calculating the length D1 of the first through hole 131 in the first direction Y, along the direction away from the base 110, can be: D1 = L + (Nm) × Δ .

[0073] The formula for calculating the length D2 of the second through hole 121 in the first direction Y, along the direction away from the base 110, can be: D2 = L + (m - 1) × Δ .

[0074] Where m represents the m-th first through hole 131 corresponding to the m-th group of the bearing members 141 along the direction away from the base 110; L represents the diameter of the rotating shaft 141a; and N represents the total number of the first through holes 131. Δ This indicates the distance that each set of the load-bearing members 141 needs to be stretched in the first direction Y.

[0075] In some embodiments, N is an integer greater than or equal to 2, preferably greater than or equal to 3, for example, it can be 5, 10, 50...100, etc.; m is a positive integer less than or equal to N; L can be less than or equal to 1 cm, for example, it can be 0.3 mm, 0.4 mm, 0.5 mm, 0.55 mm, 0.6 mm, 0.65 mm, 0.7 mm, 0.8 mm, 0.9 mm, etc. Δ It can be greater than or equal to 0.5cm and less than or equal to 3cm. For example, it can be 0.8cm, 0.9cm, 1cm, 1.2cm, 1.4cm, 1.5cm, 1.8cm, 2cm, 2.5cm, 2.8cm, etc.

[0076] In some embodiments, along the first direction Y, the spacing between adjacent bearing members 141 is greater than or equal to 10cm, and the spacing between adjacent bearing members 141 is less than or equal to 20cm. For example, it can be 12cm, 14cm, 15cm, 15.5cm, 16cm, 17cm, 18cm, 19cm, etc.

[0077] Please see Figures 1a to 1b ,and Figures 2a to 2b In some embodiments, each group of the supporting components 140 further includes a plurality of supporting members 141b arranged along the second direction X, and a display screen is connected to one of the supporting members 141b. In each group of the supporting components 141, the plurality of supporting members 141b are sequentially fixedly connected to the rotating shaft 141a along the second direction X, or the supporting members 141b and the rotating shaft 141a are integrally formed.

[0078] In some embodiments, the display screen is magnetically attached to the carrier 141b. When the splicing display device is in the display replacement state, for example, when the display screen carried by the m-th group of the N-th group of the supporting members 141 needs to be replaced along the direction away from the base 110, the distance adjustment component 130 is moved. First, the N-th group of the supporting members 141 moves relative to the (N-1)-th group of the supporting members 141. Second, the (N-1)-th group of the supporting members 141 moves relative to the (N-2)-th group of the supporting members 141... until the m-th group of the supporting members 141 moves relative to the (m-1)-th group of the supporting members 141, so that the display screen carried by the m-th group of the supporting members 141 is spaced further apart from the display screens carried by the (m+1)-th group and the (m-1)-th group of the supporting members 141. Subsequently, the rotating shaft 141a of the m-th group of the supporting members 141 is controlled to rotate counterclockwise or clockwise, thereby further separating the display screen to be disassembled (e.g., Figure 5 (as shown); Finally, release the magnetic attraction between the display screen to be disassembled and the corresponding carrier 141b, and complete the disassembly of the display screen.
